We present a simplified method for simultaneous determinations of fluorine (F), chlorine (Cl), and sulfur (S) contents and isotopic abundances in rock samples. After using pyrohydrolysis to extract F...
To evaluate the source of sulfur and the extent of seasonal and local characteristics in Seoul’s precipitation chemistry, we measured sulfur, oxygen, and hydrogen isotopic ratios of precipitation. Th...
Sulfur isotopes in vein sulfides (galena, sphalerite, and pyrite) and pyrite sulfur derived from overprinting hydrothermal systems in the altered volcanic host rocks of the Toyoha–Muine area are dete...
Atmospheric aerosol samples were collected from 1993 to 2003 at Tsuruoka, Japan, a coastal area on the Sea of Japan. Concentration of water-soluble chemical components and sulfur isotopic ratios of su...
We report the chemical composition of groundwaters—including the first data on the sulfur isotopic composition of dissolved sulfate—from the volcanic aquifers of Mt. Vulture, one of the most important...
Carbonate-hosted Pb-Zn deposits are common in the Yahyalı region (Taurus Belt) with galena the most abundant sulfide mineral. The mean d34S values for Göynük, Celaldağı Desandre, ...
Koru (Çanakkale) barite-bearing lead-zinc deposits are typical examples of the lead-zinc deposits occurring in the Tertiary volcanic rocks which crop out in the Biga Peninsula. Volcanic rocks a...
Two moss genera (Sphagnum and Polytrichum) were collected seasonally in two close (~0.45 km distance) but environmentally different locations, an Open bog and a Spruce forest at Hala Izerska (the Izer...

Microbial mats on the surfaces of modern, marine stromatolites at Highborne Cay, Ba-hamas, were investigated to assess the role of microbial processes in stromatolite forma-tion. The Highborne Cay str...
The top 20 cm of sediments at active cold seeps in Monterey Bay, coastal California,contain framboidal pyrite that occurs as infillings and pseudomorphs of the chambers of the tests of foraminifera an...
Pyrite has a poor {001} cleavage. Unlike most other minerals with a rocksalt-type structure, pyrite typically fractures conchoidally, demonstrating that parting surfaces are not constrained to the {00...

Sulfur from the troilite phase in meteorites exhibits a remarkably uniform S32/S34composition of 22.21± 0.02, which value is taken as a reference standard for OS34 measurements. Primordial sulfur is i...
